Career
He is also mentioned in Doctrine and Covenants 124:141 and was a bodyguard of Joseph Smith. Roundy played a very important part in the removal of the Latter Day Saints from Missouri. The timing of the expulsion during the winter of 1838-1839 also greatly aggravated conditions, but the more fortunate promised to assist those in need.
Quoting from a meeting held at Far West on January 29, 1839:
After their removal from Missouri, the majority of Latter Day Saints fled to Western Illinois, eventually concentrating at Commerce (renamed Nauvoo), Hancock County, Illinois.
Although the Latter Day Saints were only in Hancock County for seven years, it provided a home where they experienced many changes and developments. During this time period Roundy was active in both civil and ecclesiastical affairs
He was also one of twelve men on the Board of Control for the Nauvoo Agricultural and Mechanical (or Manufacturing) Association. Roundy protected Joseph Smith on at least two occasions.
Once, while a group of men led by William Law tried to enter the Smith home Roundy held them back with his cane.
On another occasion he accompanied Smith to Monmouth, Illinois, for a trial. Roundy helped prepare the Red Brick Store for some of the first endowments performed in Nauvoo. Shortly before the exodus from Nauvoo, Roundy was assigned to explore California (apparently the plan was never carried out) as an option for settlement in the West opposed to the Great Basin.
Roundy was bishop of the 16th Ward in Salt Lake City from 1849 until 1856.
Roundy died in Salt Lake City.
